SWINGLE'IREE-CLIP.

Specification of Letters Patent.

Patented Nov. 14, 1911.

Application filed August 31, 1910. Serial No. 579,816.

To all whom it may concern:

Be it known that I, LUoY B. HARTZELL, a citizen of the United States ofAmerica, residing at Murray, in the county of Galloway and State ofKentucky, have invented new and useful Improvements in Swingletree-Clips, of which the following is a specification.

This invention relates to swingletree clips, the object of the inventionbeing to provide a clip of this character which can be connected withthe swingletree without resorting to permanent fastenings or the like.

A further object of the invention is to construct the clip from a singlepiece of springy material such as wire, bending the same into lockingengagement with the swingletree and forming the same to provide aretaining element for engagement at one side of the tug to hold the samein its applied position.

In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views:Figure 1 is a fragmentary perspective view of a portion of aswingletree showing my improved clip applied thereto and operativelyassociated with the tug.

Fig. 2 is a side elevation thereof with parts broken away to clearlydisclose the invention.

The swingletree clip consists preferably of a single piece of springymaterial, preferably wire. The wire is bent on. itself to provide arelatively long arm 1 and'a movable arm 2. The arm 2 is connected withthe arm 1 through the coiled portion 3 which is seated in thecorrespondingly formed recess 4: at the outer end of the swingletree.The long arm of the clip extends longitudinally of the swingletree andits extremity is bent upwardly, as shown at 5, to extend through acorrespondingly formed passage in the swingletree and then downwardly toform a retaining spur 6 which is bent into the swingletree and slightlyimpressed therein to insure a perfect and most efficient fastening. Thefree or movable arm 2 of the clip extends upwardly in spaced relation tothe sWinglet-ree at one end thereof, as clearly shown in the drawing.The

extremity of the said movablearm is bent downwardly to form a keeper 7for the tug strap 8. The tug strap 8 is of usual construction, beingprovided with the eye 9 to receive the end of the swingletree, asclearly shown in Fig. 1 of the drawing. The keeper 7 extends into arecess 10 in the swingletree, and as illustrated, its lower end isoffset or hooked, as at 11, to engage a stop 12. The stop 12 ispreferably in form of a bolt which extends through the swingletree andwhich passes through the walls of the recess 10 in position to beengaged by the hooked end 11 to prevent the same from being entirelywithdrawn from the said recess 10. This construction has been found mostdesirable in that the tendency, under the spring action of the clip, ofthe same to expand is resisted and the clip is held in the most'efiicient manner in its applied position to the swingletree.

In operation of the device herein described, it may be stated that thetug 8 is threaded onto the swingletree so as to occupy the positionshown in Fig. 1 of the drawing. Under the spring action of the clip theshort arm 2 will tend to assume the full line position shown in Fig. 2so as to cause the keeper portion 7 of the arm to lie directly at oneside of the tug to hold the same against working off of the swingletree.The short arm 12 is pressed downwardly to occupy the position shown indotted lines in Fig. 2 when it is desired to remove the tug from theswinglet-ree. The construction is such that when the short arm ispressed to the said dotted line position the surface 7 at the point ofintersection of the said short arm with the keeper 7 will curve directlyinto the recess 10 so as to prevent the keeper from acting as anobstruction when removing the tug, it being understood that the eye ofthe latter can be conveniently slipped over the said curved surface.

I claim:

A swingletree clip consisting of a swinglet-ree having an opening in itsend and recesses located near said opening and one face thereof, a wirebent upon itself to provide a relatively long detachable arm and a shortmovable arm and a spring coil conacross the recess adapted to limit theout nesting said arms, the longer arm being exward movement of the shortarm. 1 tended through the swingletree and clenched In testimony whereofI afiix my signature thereagainst, and the shorter arm having inpresence of two witnesses.

an angular terminal provided with a stop LUCY B. HARTZELL. and movablydisposed in the recess, and the Witnesses:

spring coil being disposed in the end open- CONN LINN,
